Why Your Car AC Isn’t Blowing Cold Air and How to Fix It in Dubai?

Last updated on November 19th, 2024 at 11:14 pm

Dubai summers are not to be taken lightly. The thought of your car’s air conditioning system failing in the face of the city’s scorching heat can be daunting. However, with a fully functional car air conditioner, you can find relief and comfort, even in the intense heat of the United Arab Emirates. 

This post will delve into the root causes of a malfunctioning car air conditioner and provide some valuable maintenance advice, ensuring you can always stay cool on the road.

Recognising the Value of an Air Conditioning Vehicle in Dubai

In Dubai, an air-conditioned car is not just a luxury; it’s a necessity. With the intense summer heat often exceeding 40 degrees Celsius, every car needs a well-functioning air conditioning system. A reliable automotive air conditioner not only provides comfort but also plays a crucial role in health safety, reducing the risk of pain, vertigo, and heatstroke. 

Typical Causes of Your Car’s AC Not Working

After reviewing the fundamentals, let’s discuss the most common reasons why the air conditioning in your automobile is not functioning correctly. It is crucial to remember that while specific issues are simple to fix, others necessitate the assistance of an expert in auto air conditioning repair.

1. Low Levels of Refrigerant

A refrigerant shortage is one cause of an air conditioner malfunctioning. When the coolant level drops, the air conditioner cannot efficiently chill the air, similar to blood in a system. Leaks are the most frequent cause of this.

If you suspect a refrigerant leak, it’s crucial to seek professional help immediately. Attempting to handle this issue yourself can be dangerous. A professional can locate the leak, repair it, and add the correct refrigerant to recharge your system, ensuring your safety and the optimal performance of your air conditioner.

2. A Malfunctioning Compressor

The compressor powers the air conditioning system in a car. If the car’s AC compressor malfunctions, the vehicle’s air conditioning system will fail. Strange noises made by the air conditioner while it is operating and the air conditioner not turning on at all are some of the typical signs of a broken compressor. 

When compressors are not used for extended periods, such as during the winter, they fail because their refrigerant runs out and are not replaced.

Compressors also break down due to ageing, primarily because internal parts wear out or malfunction over time. Car AC repair in Dubai can help you replace a compressor through specific tools and equipments required.

3. Unclean or Clogged Condenser

Your car’s air conditioning condenser is in front of many components, including the radiator. The radiator’s primary function is to cool the compressed refrigerant in your vehicle. Dirt, debris, or even microscopic insects can clog the interior passages of this component, significantly lowering its performance.

The condenser may be clogged if the air conditioner blows hot air rather than cold air. Sometimes, cleaning the condenser yourself is as easy as lightly misting it with water. If it is highly clogged, you may want expert auto AC repair.

4. Electrical Problems

The proper operation of your car’s numerous electrical components—the fuses frequently found in vehicles—and the relays and sensors are necessary for the AC system to function correctly. Nevertheless, the system as a whole fails if these fail.

If you discover that your air conditioner occasionally operates intermittently or doesn’t turn on or off, it may have an electrical issue. Changing a fuse is a simple do-it-yourself task. However, specialised knowledge is frequently needed to troubleshoot and remedy other electrical problems.

5. Leaking or Blocked Evaporator

Before heated air enters your car’s passenger cabin, it cools it. If the evaporator is obstructing or leaking, your AC won’t chill down correctly. Weak airflow from the valves or a sweet fragrance, when the air conditioner is turned on (which may be a coolant leak), indicates that the evaporator is clogged. Since the evaporator is located deep within the dashboard, problems with it usually require specialist auto air conditioning maintenance.

Maximising Cool: How to Make the Most of Your Vehicle’s Air Conditioning

In addition to addressing any technical problems that may be causing your automobile air conditioner to overheat, you can follow a few simple tricks and procedures to help it cool down as efficiently as possible.

1. Don’t Precool

Despite what many people think, precooling your car while still parked is not a good idea. This is because the engine belt drives the A/C compressor, which pumps the refrigerant. Therefore, your engine pumps more refrigerant through the system when it runs faster, such as when you’re driving, which improves cooling.

2. Select Low-Temperature Configurations

Keep the air conditioner set to the lowest setting for optimal efficiency. This guarantees that your vehicle maintains its fuel efficiency and stays cool.

3. Allow Air to Enter Your Car

Roll down your windows and turn on your fan to let fresh air into the cabin before you crank up the air conditioning. This will also let out heated air before turning on the air conditioning.

4. Turn Off Start/Stop

Although the start/stop feature can shorten engine idling time and increase fuel efficiency, the efficiency of your car’s air conditioning system may be compromised. This is because the air conditioning compressor cannot function properly when the engine is down.

5. Activate the Recirculation System

Keeping your automobile cooler can be achieved by using the recirculation mode. When this mode is activated, the air conditioning system circulates air from within the cabin, which may be more relaxed than the hot air outside.

6. Park Wisely

Parking in the shade will help your air conditioner reach the ideal, pleasant temperature more quickly and keep the cabin cool.

7. Use of AC Curtains and Sunshade

Sunscreens can help keep your automobile cool by blocking direct sunlight. Similarly, AC curtains can block the back section, lowering the cabin’s required cooling capacity.

8. Clean Air Filters 

The airflow and cooling effectiveness of your car’s air conditioning system can be enhanced by routinely replacing or cleaning your cabin air filters.
